Answer:
29
Step-by-step explanation:
1. plug in -10 for x
-2(-10) + 9
2. multiply -2 x -10 = 20
20 + 9
3. add 20 + 9 = 29
We have the formula S= r * theta , where S is arc length , r is radius , and theta is central angle in radians
So AB= 4 * 45* π/180 = π units
Step-by-step explanation:
4x -20 + 3x +12 = 90
7x -8 = 90
7x = 98
x = 14
Angle F: 4(14) -20 = 36
Angle E: 3(14)+12= 54
Angle G : 90
